We loved Fanfan’s flat. It is a studio flat in a modern building on the top floor. The view of the city with all its skyscrapers is spectacular, and the small balcony is a plus. 10 min walk from the BTS station and the main street. Taxis are available in the area also.
It had all what we needed and even more (there is a pool and a gym but we didn’t have the time to enjoy it). There are /11 stores close to the building and also a good Italian restaurant and a bakery.
There is a washing machine and a dryer in the apartment and it was a great help.
I recommend Fanfan’s place to all who is coming to visit Bangkok
